The announcement on that homepage ... and that site ... seems to imply it is set to crease on 31st may. At least at the time i write this post.
The announcement on that site says ....
Oracle is sunsetting the MIX platform as of May 31st to coincide with the planned upgrade of forums.oracle.com. This is just one step towards building a much more engaging community and we’d like your feedback along the way.
Not sure what that glitch was. We are shutting down mix - only a very small number of people have been using it and it mostly duplicates features that will be available in the new space. We are working on a migration script to pull the content into our new forums soon after launch, so nothing will be lost.
The Mix forum operation is very random - I started to enter an idea, got near the end and it kicked me out saying I needed to log in (I was) - then went back to it and the idea summary and description fields were red, I could not enter anything into them. It clearly states it is being shutdown May 31. If we cannot use it what are we suppose to use between now and May 31? if it is still suppose to be working could someone please make sure it is operational? thanks!
We will be continuing to keep it online through May 31, but won't be doing any more bug fixes. If you have a specific topic that you'd like to see us create a forum here to cover, let me know and we'll work on setting that up for you in the new space next week.

Quick update on Mix - we've done a test migration of content into the new forums platform and it looked good. It will be brought over into a read-only space in another month or so after the relaunch so no Mix content will be lost, and users can start a new conversation and link back to the older discussions if you like.
